Hi Uwe,

thanks for the detailed instructions.

I looked into this a bit today. First of all I tried to connect
different monitors and/or two monitors at the same time and can
confirm the problem appears to be uninfluenced by that.
Only one of the video outputs is active after linux boots (so
it's not that the missing console just moved to the other screen).

Then I find a *workaround* (not a fix) that works for me: I've
just installed xfce4 and lightdm, which gave me a perfectly
working graphical console. This is a server, and I needed a
console just as a fall-back anyway to access the machine in case
of network problems, which the graphical console is fine for.

Out of curiosity CTRL-ALT-F1..F6 still does not bring up a
text console. While on F1-F6 The screen keeps on showing the F7-X11
screen, but the mouse cursor disappears. CTRL-ALT-F7 then brings
back the mouse cursor, all good.

As this workaround works for me, I'm sorry to say I will not
pursue the git bisecting tests which would consist in more work
I can afford at this time.

Again, I appreciated your answers and suggestions, both Uwe
and Kathara.

Thanks,
Chris.
